Welcome to Star Talk.

Your place in the universe where science and pop culture collide.

Star Talk begins right now.

Welcome to Star Talk Radio.

I'm your host, Neil deGrasse Tyson, your personal astrophysicist.

You can follow us on Twitter at StarTalkRadio or of course on the web at StarTalkRadio.net.

And personally, I also tweet if you're interested in my own little cosmic brain droppings and

that's at Neil Tyson.

This week we're going to break format and it is not often that we do this.

And when we do it, it's only to accommodate someone or something exceptional, something

out of the ordinary.

So on this episode of StarTalk, I'll have neither my comedian, co-host, nor an in-studio

expert with me as usual.

But instead, we'll listen together one-on-one to my exclusive interview with Edward Snowden,

a man of living controversy.

He's simultaneously referred to as a whistleblower, a fugitive, a traitor, a national hero,

an activist.

It all depends on who you talk to.

I think of him as a sort of fellow card-carrying member, the geek community, as do many geeks.

And this is a community with room for all walks of life, regardless of one's international

status on the lists of the FBI.

So what's his story?
